ALBERT HUELSMAN. OF FOND DU LAC, WISCONSIN.

WEIGHING-SCALE.

To all whom it may concern:

Be it known that I, ALBERT HUELsMAN, a citizen of the United States, and a resident of Fond du Lac, in the county of Fond du Lac and State of Wisconsin, have invented a new and Improved VVeighing-Scales, of which the following is a full, clear, and eX- act description.

The object of my invention is to provide a weighing scales having a shaft with a scale secured for rotating therewith, there being at one end of the shaft coin-controlled mechanism for releasing the shaft. Disposed substantially parallel with the scale there is a lever having a sliding weight for cooperating with the scale when the scale and the shaft have been rotated, to operative position, after a coin has been introduced in the slot of the coin-controlled mechanism. The lever is locked when the device is not in use, and means are provided for freeing the lever for use when the shaft is rotated. The scale on the shaft is exposed at the front of the weighing scales when the shaft is in inoperative position, and when the shaft is rotated to operative position the scale on the shaft is moved out of view, so that it is necessary to rotate the shaft to inoperative position, in order to move the scale to ascertain the weight by comparison of the sliding weight with the scale on the shaft.

Additional objects of the invention will appear in the following complete specification, in which the preferred form of the invention is disclosed.

In the drawings similar characters of reference indicate corresponding parts in all the views, in which Figure 1 is a front elevation of the invention; Fig. 2 is a plan view of Fig. 1; Fig. 3 is an enlarged sectional view on the line 38 of Fig. 1; Fig. 4 is a sectional view similar to that shown in Fig. 3, but with the shaft rotated to inoperative position to exhibit the scale carried thereby; Fig. 5 is a side elevation of Fig. 1; Fig. 6 is a sectional view showing the coin-controlled mechanism in locked position; Fig. 7 isa sectional view similar to that shown in Fig. 6, but with the shaft rotated to lock the lever of the weighing scales; Fig. 8 is a sectional side elevation of Fig. 7.

By referring to the drawings it will be seen that a frame is provided, having mem- Specification of Letters Patent.

hers 6, 7 and 8, a weighing lever 9 being fulcrumed at 10 on the member 8. This lever 9 has two sections 11 and 12, a sliding weight 13 being mounted for moving longitudinally on the section 11 of the lever 9, and a sliding weight 1% being mounted for moving longitudinally on the section 12 of the lever 9. At the left of the lever 9 there is an opening 15, in which is disposed a screw 16, with which meshes a nut 17, it being possible to rotate this nut on the screw 16, to adjust the lever 9, as may be desired. On the section 11 of the lever 9 there are figures 18, and the sliding weight 13 has a point 19, which extends in the direction of the figures 18 when the sliding weight 13 is moved along the section 11 of the lever 9. The sliding weight 1 1 has a point 20, which extends upward, and which points in the direction of the figures 21 on the scale 22, when the sliding weight 1% is moved along the section 12 of the lever 9. This scale is mounted on a shaft 23, journaled in bearings in the frame members 6 and 7, and it will be seen that when the shaft 23 is rotated to the position shown in Fig. 3 of the drawings, the figures 21 on the scale 22 will be rotated under the shaft 23, so that it will be impossible to compare them with the point on the sliding weight 14.

The device shown in Figs. 6, 7 and 8 is a coin-controlled mechanism for locking the shaft this mechanism consisting of a member 24, which is secured to the shaft 23, the member 2% having an opening 25, with shoulders 26 and 27, in which is normally disposed the hook 28, on the latch member 29, pivoted at 30 in the frame member 6. The member 24; also has a coin seat 31, which is disposed under the coin chute 32, and this coin seat 31 is so positioned that when a coin is disposed therein it will extend beyond the shoulder 26, to engage the curved surface 3l on the hook 28 of the latch 29. In this way the coin 33 carried by the member 24;, serves to raise the hook 28 in the opening 25 in the member 242 but when a coin is not scaten in the seat 31 the straight portion 35 of the hook 28 is engaged by the shoulder 26, which prevents the further rotation of the member 24, and the shaft 23 relatively to the frame member 6.

It will therefore be seen that in order to rotate the shaft it is necessary to insert a coin in the coin chute 32, that it will be disposed in the seat 31 and so that it Will engage the curved portion 3% of the hook 28, to permit the member 2+1, the shaft 23, and the scale to rotate relatively to the other parts. After the coin has been introduced in the chute 32, the shaft 23 mav be rotated, by means of the handle 36, which is secured thereto, and to this handle 36 there is also secured a cam 37, for engaging the locking lever 38, for fr eing the locking lever 1 om the pointer 39 on the lever 9, this locking lever 38 having a recess d0, in which the said pointer 39 is disposed, when the handle 36 is raised to the position shown in -1 of the drawings. A spring d1 is provided. for holding the locking lever 38 with the pointer 39 embraced by the locking lever around the opening 4-0. In this way the raising of the latch 29 by means of the coin not only permits the shaft 23 to rotate, carrying with it the scale 22, but it also permits the spring ll, to move the locking lever 38 forward, and into engagement with the pointer 39, at the right of the lever 9.

hen coin is inserted in the chute 32 it will fall to the coin seat 31 and the weights 13 and ll having been adjusted, the handle so is raised to rotate the shaft 23, the scale and the member 2l. A comparison of the weights 13 and 1d and the scale 22 may then be made to determine the weight on the scale. With the rotation of the member 2i the catch l3 on the arm l2 pivoted at as engages the point at of the member 2-t and the scale 2 is held in this position until another coin is inserted in the chute The lever 9 is also held against movement by the engagement of the cam -17 with the arm 18 for moving the arm l8 forwardly against the resiliency of the spring 49, this arm l8 carrying a stud 50 with a head 51 for engaging the lever 9. This is all shown in Fig. 7 of the drawings. The parts now remain in this position until another coin is inserted in the chute 32 when this second coin will press against the pivoted arm l2 for moving the catch d3 carried by the arm 12 out of engagement with the point viii of the member This arm L2 is pivoted at l5 and is held yieldingly with its catch 43 engaging the point by a spring The member 2%, the shaft and the scale 22 are prevented from rotating when the catch engages the point at The second coin having been inserted in the chute it presses aside the arm 4-2 and the catch 3 and permits the member 2%, the shaft 23 and the scale 22 to rotate by the weight of the member 21 and the scale 22, the spring l9 and the cam 4:7 assisting this movement. The member 2% is then locked by the latch member 29, but the member having moved sufliciently far to carry the cam d7 rearvvard, permits the rearward movement of the stud 50 and its head 51 to free the lever 9. With the movement of the handle 36 the scale may be operated in the manner heretofore described.
